Azure Linux 3.0 Security Update: python-tensorboard / pytorch (CVE-2021-22569)

medium Nessus Plugin ID 295632

Language:

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of python-tensorboard / pytorch installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2021-22569 advisory.

 - An issue in protobuf-java allowed the interleaving of com.google.protobuf.UnknownFieldSet fields in such a way that would be processed out of order. A small malicious payload can occupy the parser for several minutes by creating large numbers of short-lived objects that cause frequent, repeated pauses. We recommend upgrading libraries beyond the vulnerable versions. (CVE-2021-22569)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
